Selective catalytic reducer

In modern diesel engines, subsequent treatment of the exhaust gases produced as a result of combustion is required to meet the demands of the Euro 6 standard. Here, an aqueous urea solution (Adblue/DEF) is dosed into the exhaust gas system that reduces nitrogen oxides in the catalytic converter. Since the additive freezes at low temperatures (from -11°C/52F), all components carrying Adblue must be heated. In this segment we offer solutions for heating systems positioned at specific points or over a surface based on PTC or regulated fixed resistor technology. In the case of PTC Technology, we generally use our patented manufacturing method, which guarantees a highly-efficient transfer of energy to the medium to be heated. For applications on a surface structure, we draw on our years of experience in the field of plastic coated (fixed resistor) lead frames. In combination with our patented control system for lead frames, we can provide you with a low-cost solution for surface applications. The high degree of freedom in terms of shape design allows considerable flexibility when integrating the heating system in the customer’s SCR module. In addition to complying with statutory requirements in terms of required thaw quantities/times, our heating systems also meet increasing demands for sealing tightness and service life in direct contact with Adblue/DEF due to efficient application of the heat output. Various output categories are available to choose from.
